CHARLES E. PAGE, LOS ANGELES, CALIFORNIA, ASSIGNOR, IBY DIRECT AND MESNE ASSIGNMENTS; T0 ECONOMY DISPENSER CORPORATION, 013 LOS ANGELES, CALI- FOBNIA, CORPORATION 01! NEVADA msrnnsmo n'n'vron Application Med January 15, 1927. Serial 80. 161,838.

This invention relates to a dispensing dovice such as used for dispensing small quantitles of groceries in bulk or other commodities. While the dispensing device may d be used for dispensing any kind of food or other substance, in the present specification l have described an embodiment of the de vice which is particularly adapted for dis pensing ground coffee or other granular mam terial. The type of dispensing device to which my invention relates includes in lts constructiona curved closure mounted upon a shaft and which swings across the'outlet.

from the receptacle for the material to be dispensed. The device also includes a second closure, and the movements of these closures are correlated so that when one is open the other is closed, and vice versa.

' The general object of my invention is to.

W improve the general construction of a dispensing device of this type and particularly to provide improved means for securing the curved closure to its shaft, and for connecting the closures to cause them to operate in ill a correlated manner.

Further objects of the invention will ap pear hereinafter...

The invention consists of the novel parts and combination of parts to be described to hereinafter, all of which contribute to produce an eficient dispensing device.

A preferred embodiment of the invention is described in the following specification, while the broad scope of the invention is on pointed out in the appended claims.

In the drawings:

Figure 1 is a vertical section through'the lower end of a dispensing device embodying my invention, the u per portion of the dis easing device being roken away.

igure 2 is a plan of the head or bottom of the dispensing device removed from the body of the device.

Figure 3 is a vertical section taken about in the plane of the line 3-3 of El re 1. a

v Figure 4 is a detail p and shows the shaft 0 the device in section on the line 4-4 of Figure 2.

Referrin to the parts, 1 represents the M container or the material or substance to be dispensed, for example,coifee; In apply ing my invention, I provide a removable head or bottom 2 for this container, said head having an outlet 3 which is preferably artially bro en away.

of tubular form. This outlet extends down from the head 2 which is of curved or cup form. The head and tubular outlet 3 are preferably made of light sheet metal.

According to my invention I provide a engage the edge of the inner end of the outlet. The face of the closure is curved in two directions so that the closure may sweep across the outlet and engage the edge of the outlet with its convex face. In this way the contact between the closure and the outlet is not formed between the faces of two plates but between the edge of the outlet and the face of the closure.

in order to accomplish this it provide a closure at which is preferably formed of a plate of sheet metal bent into the form of sector. The sector is substantially a half circle in form. That is to say it extends through 180. The sector includes also a chord plate 5 which connects the ends of the curved plate of the sector. For this purpose the ends of the chord plate are formed with slots 6, and the ends of the curved the closure are bent around and hoo ed into these openings 6 from the upper side. See Figure 1. This sector 4 is attached to a transverse shaft 7 which extends horizontally through the head 2. In order to secure. the sector to the shaft I prefer to form the chord plate with two integral straps 8 which pass over theupper side of the shaft and an integral strap 9 which passes under the lower s1de of the shaft. In addition to this the shaft is formed with a neck 10 of reduced dimensions and this neck is flattened or mutilated so as to resent a flat face 11 which is engaged by t e strap 9. In this way late of the outlet; this fit two shoulders 12 are formed which engage the edges of the strap 9 and this keeps the closure from moving longitudinally on the.

shaft. The neck 10 by reason of the flat face 11, has a D form that operates to fix the, sector on the shaft so that it will swing over the opening or outlet 3 when the lever 13 of the shaft is actuated. This type of closure is very effective as a closure for a dis ensing device and it will operate efiectivefy on a 16. For this purpose granular substance such as-sugar or ground cofiee. This form of closure and co-operating outlet avoids the use of two surfaces which come to ether and between which the fine ains o the material may become lod e n adapting a closure of thiskind to a dispensing evice to dispense a given or meas.

'ured quantity, I rovide the lower end of the outlet 3 with a c osure 14. This closure is in the form of a disc which is attached at one edge so that it can swing or rotate onan axis extending substantially parallel to the axis of the outlet and at right angles to the shaft 7. In the present instance the edge of this disc 14 is attached to a vertical shaft 15 which is rotatably mounted in the head 2. and extends up into the head at the side of the outlet, see Figure 3.

Between the closures 14 and 4 I provide a connection which operates to insure that when. one of the closures is open the other one will be closed. For this purposeI provide a rigid arm 16 carried by the upper end oftheshaft 15, said arm having a longitudinal slot 17. Moving with the shaft 7 I provide a dog to co-o crate with this arm provide an extension or do 18 which may be formed integral with one e ge ofthe sector of the closure 4 and this finger or dog 18 projects up into the slot 17 With this organization of parts it will be evident that-the movements of the closures 4 and 14 are correlated. The arm 16 and the dog 18 are so positioned that when the disc 14 has closed the lower end of the outlet 3, the closure 4 will be in an open position and vice versa.

In the normal position of the closures the disc 14 will. be in alinement with the lower end of the outlet 3 .and the closure 4 will be in an' open position. That is to say the upper end of the outlet will be in communication with the interior of the receptacle 1. At this'time the lever-'13 will be in a position substantiall 180 from that in which it is shown in igure 1. By rotatin the lever around to the position indica in Fi re 1 the closure 4 will operate to close e upper end of the outletfl3 and at the same t1me the do 18 will actuate the arm 16 to swing the 11d or closure 14 to its open position, and this is indicated in dotted lines in Figure 2. a

The opening movement of the closure 14 is finally, arrested throu h the agency of a stop finger 19 which pro iects laterally from the arm 16. This stop finger strikes the inner face of the head 2 and in this way sto s the opening movement.

emovement of the lever in this direction is resisted by coil spring 20, see Figure 3, which is disposed around the shaft 7. One end.of this spring is held in a small socket 21 formed on the inner side of' the head 2,

and the other end is fixed to a in 22, pro jecting from the side of the slut t. In other words, the spring exerts its force in the direction to hold the closure 14 closed; In order to limit the closing movement of the closure 14, one edge of this closure is provided with a small projection or nib 23 whichengages the lower end of the outlet 3 when the disc 14 is completely closed and in this way prevents furt ier movement of the lid.

The lever 13 may be made integral with the. shaft 7. In placing the shaft 7 in position its end -is passed through an opening 24 in the side of the head 2'ncar the shaft 15 and the end of shaft 7 which is rounded, is received in a small socket 25 which is off-set outwardly in the wall of the head 2 on the op site side.

11 order to retain the shaft 7 it is provided with a reduced neck at the point 25 and around this neck a split ring or washer 26 is received. This washer prevents the shaft from moving outwardly through the opening 24. The details of this construction are illustrated-in Figure 4.

It is understood that the embodiment of the invention described herein is only one of the many embodiments this invention may take, and I do not wish to be limited in the practice ofthe invention, nor in the claims, to the particular embodiment set forth.
